Which three types of subatomic particles make up an atom, and what are their respective charges?

• A. Protons (positive), neutrons (neutral), electrons (negative)
• B. Protons (neutral), neutrons (negative), electrons (positive)
• C. Protons (negative), neutrons (positive), electrons (neutral)
• D. Protons (positive), neutrons (negative), electrons (neutral)

Answer: (A)

Verified step by step guidance

1. Identify the three fundamental subatomic particles that constitute an atom: protons, neutrons, and electrons.
2. Recall the charge associated with each particle: protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
3. Understand that protons and neutrons reside in the nucleus of the atom, while electrons orbit around the nucleus in electron clouds or shells.
4. Recognize that the number of protons defines the element, the number of neutrons contributes to isotopes, and the number of electrons affects the atom's charge and chemical behavior.
5. Match the correct charges to each particle to select the accurate description: Protons (positive), neutrons (neutral), electrons (negative).
